Lesson 9
More and Less than 1%
Let’s explore percentages smaller than 1%.
Problem 1
The student government snack shop sold 32 items this week. For each snack type, what percentage of all snacks sold were of that type?
snack type | number of items sold |
---|---|
fruit cup | 8 |
veggie sticks | 6 |
chips | 14 |
water | 4 |
Problem 2
Select all the options that have the same value as \(3\frac12\%\) of 20.
A:
3.5% of 20
B:
\(3\frac12 \boldcdot 20\)
C:
\((0.35) \boldcdot 20\)
D:
\((0.035) \boldcdot 20\)
E:
7% of 10
Problem 3
22% of 65 is 14.3. What is 22.6% of 65? Explain your reasoning.
Problem 4
A bakery used 30% more sugar this month than last month. If the bakery used 560 kilograms of sugar last month, how much did it use this month?
Problem 5

Problem 6
A certain type of car has room for 4 passengers.
- Write an equation relating the number of cars (\(n\)) to the number of passengers (\(p\)).
- How many passengers could fit in 78 cars?
- How many cars would be needed to fit 78 passengers?
